It is open to atmosphere to allow boost diaphragm to move down as turbo pressure increases. I think Bosch went a little over the top engineering it to keep shmoooo from entering as boost drops and pressure beneath diaphragm momentarily drops below ambient. Bung the washer back and tappy tap tap the housing to retain it then bung the rubber Johnny back on
